A new method to search for neutrinos from the Galactic Center with the IceCube detector — •Jan-Patrick Hülß, Sebastian Euler, and Christopher Wiebusch — RWTH Aachen

The IceCube detector is located at the geographical South Pole and is therefore primarily sensitive to neutrinos from sources in the northern hemisphere. Signals from the southern hemisphere like the Galactic Center (declination -29°) are hidden in the overwhelming background of down-going atmospheric muons. This background can be reduced by selecting muon tracks which start inside the detector. These events must be neutrino induced. The selection uses the outer part of the IceCube detector as a veto. Therefore specialized filters and algorithms have been developed to enlarge the field of view of IceCube with the DeepCore detector. The DeepCore detector is currently being installed in the central lower region of IceCube. As a first approach we apply these methods to the IceCube installation from 2008 with 40 strings in order to search for neutrinos from the Galactic Center and to experimentally verify the performance of the methods.
